English to German Law/Patents Patents Patentansprüche

1. An automated, computerized method for determining illumination in an optical color image, comprising the steps of:
identifying depth information in the optical image;
generating a linear mega-token for the optical color image as a function of the depth information; and
utilizing the linear mega-token to analyze illumination flux in the image,
wherein a linear mega-token is a linear token comprising several adjacent uniform tokens,
wherein a uniform token is a connected region of the optical color image wherein adjacent pixels of the region have differing color measurement values that fall within a cylinder in color space from a dark end to a bright end along a positive slope, wherein this cylinder is predicted by a bi-illuminant dichromatic reflection BIDR model, according to which the appearance of a single-color surface under all combinations of an incident illuminant and an ambient illuminant is represented by a BIDR cylinder in color space,
wherein the linear mega-token comprises only adjacent tokens that fall within a BIDR cylinder for the linear token.

2. The method of claim 1, wherein the depth information in the optical color image is obtained from a disparity map for the optical color image.

3. The method of claim 2, wherein the disparity map is obtained from a stereo image pair.

4. The method of one of the claims 1 to 3, comprising the further step of utilizing the linear mega-token to adjust a pixel color value as a function of BIDR model information color values, in a color correct image manipulation step.
